Abstract

It is argued that Carnap was not a complete verificationist in the Aufbau despite the widespread view that he was. That doctrine would be intrinsic to constructionalism only if either of two additional assumptions are made, and there is no reason to believe that Carnap made these assumptions. Further, in the Aufbau Carnap did not demand verifiability independently of constructionalism, and his clear rejection of verifiability in Pseudoproblems counts heavily against his ever having accepted it in the Aufbau.
